JOHN W. KENDRICK, OF CHICAGO, ILLINOIS.

TIE-PLATE WASHER.

To all whom it may concern:

Be it known that I, JoI-iN IV. KENDJRICK, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Tie-PlateWashers, of which the following is a specification.

The principal object of my invention is to provide a new and improvedwasher adapted to be used under the heads of the spikes that are drivendown into a railway tie to hold the rail in position thereon.

My invention is particularly adapted to be used with screw spikes.

A further object of my invention is to provide a washer that shallsupport the head of the spikes on the opposite side thereof from theedge of the rail base.

These and various other objects of my invention will be betterunderstood on reading the following specification and claims, when takenin connection with the accompanying drawings, in which- Figure 1 is across section of a rail, tie plate and other parts embodying myinvention. Fig. 2 is a top plan View of the same. Figs. 3 and 1 areperspective views of the double washer shown at the left of Fig. 2.Figs. 5 and 6 are perspective views of the single washer shown at theright of Fig. 2. Figs. 7 and 8 are perspective views of a modified formof the single washer. Figs. 9 and 10 are perspective views of a modifiedform of the double washer, and Fig. 11 is a perspective view of the tieplate.

In the particular embodiment of my invention disclosed in theaccompanying drawings, I have designated the rail by the referencenumeral 15, the base thereof by 16 and the tie plate by 17. Littleridges 18 are formed on the under side of the tie plate, the intentionbeing that they shall become embedded in the top surface in the tie andthus hold the tie plate more securely in place.

- At one side of the tie plate, I have shown a ridge 19 on the topsurface adapted to lie against the edge of the rail base 16 and form anabutment therefor. The holes in the tie plate are indicated by thereference numeral 20. I have illustrated two holes on one side, and onehole on the other side of the rail, it being a somewhat common practiceto have two spikes on the outer side of the rail, especially uponcurves. The upper surface of the tie plate slopes gently toward the lat-Specification of Letters Patent.

eral edges from the edges of the rail base, as indicated by thereference numeral 21. The screw spikes 22 have the heads 23 adapted tooverhang the edges of the rail base 16, with the squared parts 24:adapted to receive a wrench.

. The washer consists of a circular areshaped member 25, adapted to reston the tie plate and having its ends beveled, as indicated at 26, toaccommodate the abutment rib 19. The arc-shaped member 27 forms acontinuation of 25, and is adapted to lie upon the rail base 16. Justwithin the member 27 is an open space 28. Concentric with the arc-shapedmember is a similar member 29 surrounding the hole 39 for the spike.Between the two parts 25 and 29 is a space 30. On its upper side the tieplate washer has a conical concave seat 31 adapted to receive the head23 of the spike. Around this concave seat 31 is a flange 10, whichcompletely surrounds the head 23 of the spike.

The foregoing description of the tie plate washer applies equally wellto either the single or double forms shown in the drawings.

In addition to the description just given, it should be noted that thedouble washer illustrated in Figs. 3 and 4: has its two parts connectedtogether at 32, and that it is re cessed at 33 on its top surface, inorder to effect a saving of material.

Referring to the modification shown in Figs. 7, 8, 9 and 10, it will benoted that the under surface of each washer consists of a part 34,adapted to lie upon the tie plate, and a part 36 adapted to lie upon theedge of the rail base, these two parts being joined together by theoblique parts 35, which fit upon the rib 19. On its upper side, eachwasher has a complete conical concave surface 37, which. constitutes aseat for the head 23 of the spike. The hole 38 for the spike is acomplete circle, thus surrounding the spike at all points within theseat 37.

It will be observed that I have invented a tie plate washer whichsupports the head of the spike equally on all sides, and that the washerengages the rail base in such a way as to prevent its rotation aroundthe spike.

I claim:

1. A tie plate washer having a part adapted to lie upon the tie platebeside the rail base, another part adapted to lie upon the edge of therail base, and an intermediate part conforming to the shape of an abutment ridge on the tie plate.

2. A tie plate washer having a part adapted to lie upon the tie platebeside the rail base, another part adapted to lie upon the edge of therail base, and an intermediate part conforming to the shape of anabutment ridge on the tie plate, said washer having two holestherethi'ough for spikes.

A tie plate washer having a thick part on one side adapted to restdirectly upon the tie plate, a thin part upon the other side adapted torest directly on the rail base and having a concave conical seat adaptedto receive the head of a screw spike, said thick part of the washerhaving an annular channel on the underside thereof.

4. A tie plate washer having a thick part 20 on one side adapted to restdirectly upon the tie plate, a thin part on the other side adapted torest directly on the rail base, and having two concave conical seatsadapted to receive the heads of screw spikes, said thick partof theWasher having a channel on the under side thereof.

In testimony whereof, I have subscribed my 11211110 JOHN \V. KENDRICK.
